Frequently asked questions

Do you repair out-of-warranty Delta solar inverters?

Yes. Out-of-warranty Delta inverters are repaired at component level, which is usually much cheaper than replacing the inverter.

My Delta inverter shows an error code — can you help?

Send us the error code and a photo of the display on WhatsApp. Many Delta errors are caused by site conditions and can be resolved without opening the inverter; others need workshop repair.
